Warnings Provided in the Instruction Manual
Notes that have been described to the manual and their description places are shown
as follows.
Use in humid and dusty place
• Do not use the system near a sink, a humidifier, or any place near water, in a humid
basement room, or a dusty place or a place subject to fumes. A failure to heed this
precaution can result in electric shock or fires.
Electric Shock from High Voltages
• Internally, the system uses maximum voltages of AC 240 V and DC 15 kV.
Touching any of the internal components or circuits when the system is powered on can
potentially result in severe injury or death from electric shock.
Do not remove the cover from the system.
When opening the electron gun and other components for maintenance purposes, be sure
to turn off the earth leakage breaker and the power switch, and unplug the power cord
before commencing the work.
Electric Shock from Improper Grounding
• When connecting the main unit to the power supply, use the grounded three-prong
power cable supplied with the system.
Using a power cable not supplied with the system can potentially cause electric shock.
Also, be sure to connect the power cable to a grounded three-prong power outlet.
If a grounded three-prong power outlet is not available for some reason, provide a
grounded three-prong table tap or a conversion adapter. In such a case, be sure to
provide an appropriate grounding. Use a grounding wire with a minimum core wire size
of 2.0mm. In addition, for connection use a minimum screw diameter of M4 and a
thread count of 3. Be sure to plug it in securely.
